This project is used to verify the solution verification board design of FDC2214RGHT, a special sensor for Lichuang Mall.
The FDC2214 is a family of noise- and EMI-resistant, high-resolution, high-speed, multi-channel capacitive-to-digital converters for capacitive sensing solutions. Has four channels.
This design leads out the I2C interface for communication between the chip and the microcontroller, making it easy to connect to the microcontroller development board.
